Stunning video of a shark getting eaten by a grouper fish

The shark has become the most feared creature in the ocean, with much thanks to real-life and fictional shark attacks sinking their teeth into our psyche. But the video below shows that those great whites aren't the greatest thing we have to worry about in the water.

The video depicts a grouper fish and a 4-foot-long shark circling each other next to a boat. Clearly only one fish is going to make it out alive, and the two dance their maritime battle for survival. But when one fisherman nearly reels in the shark, its doom is played out quickly as the grouper sinks its jaws into its prey--swallowing the shark whole in one swift bite.
